Head rotates in the wrong direction while riding a horse

It seems to actually rotate the player's head around its body to match the position of the camera around the horse. So when you look to the left of the horse, your character looks to its left too, no matter the orientation of its body compared to the camera.

Note that this is only noticeable on non-saddled horses, as saddled ones will rotate to face where you look.
